My bike gets dropped off tomorrow. Unfortunately i'm doing military training until june so it will be outside in the pollen storm here in texas. I see walmart sells a cover for about $25. Do you guys think I'll need a L or XL for my fatboy? All I got around me is a walfart and pep boys.
Don't go cheap on the cover b/c they have to breathe. Can't you go back to the HD shop & get one (call & have delivered w/bike)? Recommend HD's outdoor cover - you won't regret it.
DOWCO makes HD covers...at least they used too. Anyway they make a VERY good cover. If you do not mind paying the HD Tax get one with your bike like Iceman suggested. You did not mention if you were going to be there for delivery or if you were leaving the same day as delivery. If you have a few extra days look for a Guardian Weatherall and its lockable to your bike. By far one of the best covers out there and many places will Fedex it to you.
I bet a large will be fine. I got an XL HD cover for my Herritage Classic. I was concerned it might be too big but with the windshield on it's a perfect fit. Don't go cheap on the cover...you'll be sorry if you do.
